Demonstrators At The Democratic National Convention in Chicago, 1968

Hippie demonstrators line up to face a row of National Guard soldiers along the Grant Park sidewalk on Michigan Avenue across from the Hilton Hotel during the Democratic National Convention, Chicago, Illinois, August 26, 1968. One of the protestors, a young man smoking a pipe, seemingly offers a soda can of Fresca to a stoic Guardsman as another protestor, a young woman leans in while smoking a cigarette.
